The methods of FIGS. 8C and 9 are self-explanatory with reference to the above discussion of FIG. 8B.

Reference is now made to FIG. 10A, which is a simplified flowchart illustration of a preferred method of receiving a satellite broadcast transmission within a moving vehicle, useful in conjunction with the system of FIG. 1. FIG. 7B, described above, illustrates a typical situation in which the method of FIG. 10A might be particularly useful. The above description of FIG. 7B explains concepts such as broadcast footprint, which are useful in understanding the method of FIG. 10A. It is appreciated that an airplane is a typical example of a moving vehicle for the purposes of the method of FIG. 10A, but any other appropriate moving vehicle may also be used. The method of FIG. 10A preferably comprises the following steps:

Within a moving vehicle, a satellite broadcast transmission is received from a first satellite using first reception parameters (step 280). The first reception parameters typically include information necessary to successfully receive and tune the satellite broadcast transmission from the first satellite, such as, for example, one or more of the following: the position of the satellite; one or more frequencies used by the broadcast transmission; polarization parameters of the broadcast transmission, as are well known in the art; and other suitable parameters, particularly parameters well known in the art.

The broadcast transmission may include any appropriate broadcast transmission such as, for example, a television broadcast or a data broadcast such as a broadcast of computer data or computer software.

A current position of the moving vehicle is determined (step 285), based, for example, on inertial navigation or GPS information, as is well known in the art. Based typically on the results of step 285 and parameters of the moving vehicle, such a direction of travel and speed thereof, a future position of the moving vehicle is computed (step 290), typically using methods well known in the art A check is made to determine whether the future position of the moving vehicle, computed in step 290, is within a second broadcast footprint of a second satellite (step 293). If the future position is not within the second broadcast footprint, the method of FIG. 10A preferably continues with step 300, described below. If the future position is within the second broadcast footprint, the broadcast reception parameters used within the moving vehicle are adjusted to correspond to the broadcast reception parameters of the second satellite, thus causing a broadcast transmission from the second satellite to be received (step 296).

The satellite broadcast transmission being received is utilized within the moving vehicle (step 300). Preferably, as described above with reference to FIG. 7A, the at least one entertainment channel is provided to the at least one passenger without passenger intervention when the moving vehicle passes from the first footprint to the Reference is now additionally made to FIG. 10B, which is a simplified flowchart illustration of a preferred method of operation of steps 290 and 296 of FIG. 10A. Preferably, during step 290 of FIG. 10A, a transition time is computed, at which time the moving vehicle is expected to move into the second broadcast footprint (step 305). Preferably, during step 296 of FIG. 10A, the broadcast reception parameters are adjusted at the transition time (step 310).

Reference is now made to FIG. 11, which is a simplified flowchart illustration of an alternative preferred method of receiving a satellite broadcast transmission within a moving vehicle, useful in conjunction with the system of FIG. 1. FIG. 7B, described above, illustrates a typical situation in which the method of FIG. 11 might be particularly useful. The above description of FIG. 7B explains concepts such as broadcast footprint, which are useful in understanding the method of FIG. 11. It is appreciated that an airplane is a typical example of a moving vehicle for the purposes of the method of FIG. 11, but any other appropriate moving vehicle may also be used. The method of FIG. 11 preferably comprises the following steps:

Within a moving vehicle, a satellite broadcast transmission is received from a first satellite, and is designated as a primary signal (step 312). A satellite broadcast transmission is also received from a second satellite, and is designated as a secondary signal (step 315). A measure of quality is used to compare the primary signal to the secondary signal (step 320). Any of a wide variety of measures of quality may be used as the measure of quality in step 320 such as, for example, one more of the following: signal strength; variations in signal strength; error rate; or any other appropriate measure of signal quality well known in the art.

If the measure of quality of the secondary signal is not higher than the measure of quality of the primary signal (step 323), the method of FIG. 11 continues with step 330, described below. If the measure of quality of the secondary signal is higher than the measure of quality of the primary signal (step 323), the second satellite transmission becomes the primary signal (step 326) and, typically, the first satellite transmission becomes the secondary signal.

The primary signal is utilized within the moving vehicle (step 330). Utilizing the primary signal within the moving vehicle may comprise any appropriate type of utilizing such as, for example, utilizing the signal within the system of FIG. 1. Preferably, as described above with reference to FIG. 7A, the at least one entertainment channel is provided to the at least one passenger without passenger intervention when the moving vehicle passes from the first footprint to the second footprint, and the broadcast signal from the second satellite becomes primary.

FIG. 7B, described above, illustrates a typical situation in which the method of FIG. 12 might be particularly useful. The above description of FIG. 7B explains concepts which are useful in understanding the method of FIG. 12. It is appreciated that an airplane is a typical example of a moving vehicle for the purposes of the method of FIG. 12, but any other appropriate moving vehicle may also be used. The method of FIG. 12 preferably comprises the following steps:

Step 312, described above with reference to FIG. 11, is preferably performed. Upon receiving an external signal, a satellite broadcast transmission is received from a second satellite, and is treated as a primary signal (step 335). The external signal may typically be an external signal from a ground-based station, typically a station which is tracking a position of the moving vehicle, or an external signal from a satellite.

A satellite broadcast is received from the first satellite when the vehicle is within the first broadcast footprint and from a second satellite when the vehicle is within the second broadcast footprint (step 400).

The first channel identification code is employed to generate billing information for a first vendor, such, for example, a first broadcaster, for a time period during which a subscriber unit in the moving vehicle is tuned to the channel within the first footprint, that is, is tuned to the channel being broadcast from the first satellite (step 405). Similarly, the second channel identification code is employed to generate billing information for a second vendor, such, for example, a second broadcaster, for a time period during which a subscriber unit in the moving vehicle is tuned to the channel within the second footprint, that is, is tuned to the channel being broadcast from the second satellite (step 410). The billing information which is produced in steps 405 and 410 may be used, for example, as described above with reference to FIG. 15 for billing information therein.

The method of FIGS. 16A and 16B also optionally comprises the following steps:

A determination is made that the moving vehicle is at a common border between the first footprint and the second footprint (step 415).
